IMPROVED WIN DOW-SASH SUPPORTER.

T0 ALL PERSONS T() WIIOM THESEYIRESENTS SHALL COME:

Be it known that I, BLANEY E. SAMPSON, of Boston, in the county of Suffolk, and State of Massachusetts, have invented a new and vuseful or Improved Window-Sash Supporter; and do herebj7 declare the same to be fully described in the following specification and represented in the accompanying drawings, of which Figure I is a vertical section of it as applied to the lower sash of a window and its frame. i

Figure 2 is a section of it as applied to the upper sash of a window and its frame.

In the said drawings, is the lower and B the upper sash. C is the window-frame, formed in the usual manner except that there need be no balance-weight chambers in the said frame. Each sash has a recess, a, formed in one edge of it, such recess being for the reception of an inclined plane, b, (arranged at its upper part in manner as re resented and a'roller, c', carried b a turca-ted bar or carrier-rod, 0l rovided with a s rino* c forcing it upward. The said bar as applied to either sash, is to have at least one arm,f, (or its equivalent,) extending from it horizontally through a vertical slot, g, made in the side bar t of the sash. In respect to the carrier-rod or bar d ofthe upper sash, I prefer to provide such bar with two of such arms, as shown atff, they going through separate slots gi', one ot' which is made above and the other below the horizontal cross-bar z' at the middle ot' the sash. The object/otl the two arms to the furcated bar of the upper sash is to enable a person to more readily' pull the bar downward when the lower sash is fully raised and the upper sash is about half way down. An e'ort to raise either sash will cause the roller to travel down the inclined plane. As soon as the 'powe` applied to the sash to elevate it may be removed from it, the spring will elevate the roller or force it up the inclined plane and against the jamb or inside edge of the window-frame. The conjoint action of the spring, roller, and inclined plane will cause the sash to be supported in position inthe frame. Thus my invention renders balance-weights and cords to the sash unnecessary. A lever-latch, Z, is arranged within the window-frame near its middle, such latch being formed as represented. It is supported on a fulcrum, m, and has a spring, n, arranged in the frame, so as to press the lower arm or tail of the latch toward the window-sash. At the upper part ofthe sash and inclined plane there is a catch, o, for the latch to operate with, for the purpose of holding the sash down, or prevent it from rising without the roller being first moved downward. The roller, when in its highest position with respect tothe sash, will press against the tail of the springdatch, so as to maintain the latch hold of the catch. On depression of the roller the spring of the latch will be free to operate and throw the latch olf the catch. Y

What I claim as myinvention is as follows:

I claim the combination as Well as the arrangement of the inclined plane b, the roller e, the carrier-rod d, its armf, or arms ff', the spring e, and the spring-latch l, arranged in the windowframe, the whole being substantially as described.
